13 hours ago Physicians have noted dyspnea in severely ill asthmatic patients to be associated with fright or panic; in more stable patients dyspnea may reflect characteristics including lung function, personality and behavioral traits. This study evaluates the symptom of dyspnea in 32 asthmatic patients twice: first when acutely ill and again after an initial response to therapy. >> Go To The Portal
Dyspnea is a symptom of asthma. Environmental pollutants such as chemicals, fumes, dust, and smoke can make it more difficult for people with dyspnea to breathe. People with asthma may find that exposure to allergens such as pollen or mold may trigger episodes of dyspnea.
Acute dyspnea—breathing discomfort occurring within hours to days—is a common cause of emergency department visits and hospital admissions and may be a sign of cardiorespiratory decompensation among hospitalized patients.
Acute dyspnea is most likely caused by acute myocardial ischemia, heart failure, cardiac tamponade, bronchospasm, pulmonary embolism, pneumothorax, pulmonary infection in the form of bronchitis or pneumonia, or upper airway obstruction by aspiration or anaphylaxis.
Initial Assessment of Patients with Dyspnea Assess airway patency and listen to the lungs. Observe breathing pattern, including use of accessory muscles. Monitor cardiac rhythm. Measure vital signs and pulse oximetry.
Dyspnea is treated by addressing the underlying disease or condition. For example, if dyspnea is caused by pleural effusion, draining fluid from inside the chest can reduce shortness of breath. Depending upon the cause, dyspnea can sometimes be treated with medication or by surgical intervention.
The experience derives from interactions among multiple physiological, psychological, social, and environmental factors, and may induce secondary physiological and behavioral responses." Dyspnea is considered acute when it develops over hours to days and chronic when it occurs for more than four to eight weeks.

Dyspnea in acute asthma reflects both uncoupling of inspiratory effort from inspiratory flow (airway narrowing) and hyperinflation. Both uncoupling and hyperinflation are promptly relieved by treatment. Subsequently in stable subjects, lung function is no longer a major determinant of dyspnea.
The rise in respiratory rate increases the work of breathing, and the obstructed outflow of air in COPD leads to worsening hyperinflation and heightened stimulation of mechanoreceptors. This results in more dyspnea, which may make the patient breath faster and worsen the hyperinflation still more.
Dyspnoea (also is known as dyspnea, shortness of breath or breathlessness). "Is a subjective sensation which probably develops as a result of the integration of signals from the central nervous system and some peripheral receptors."
A designated individual must check the entire facility, including bathrooms, before exiting, making sure to close all doors when leaving to try to contain a fire or other disaster. An AED may save the life of a victim in cardiac arrest.
The best way to treat a suspected diabetic emergency in a conscious patient is to. administer glucose tabs. An adult who suffers sudden cardiac arrest has the best chance of survival if CPR. is started immediately and an AED is used within 4 minutes.
Atropine reduces secretions, increases respirations and the heart rate, and relaxes smooth muscle.
If a fire is suspected, immediately disconnect oxygen supplies or turn off oxygen tanks to prevent an explosion. 4. Make sure smoke alarms are located throughout the facility, checked periodically, and replaced as needed. 5.
Syrup of ipecac causes vomiting for the expulsion of some poisons. Activated charcoal is an antidote that is swallowed to absorb some ingested poisons. Narcan is a narcotic antidote administered intravenously for drug overdoses that acts to raise blood pressure and increase the respiratory rate.
Emergency medical treatment is needed if an individual has any of these symptoms: sudden onset of severe dys pnea. loss of ability to function due to shortness of breath. chest pain. nausea. Not all cases of dyspnea call for immediate medical treatment, but shortness of breath can indicate serious medical problems.
Environmental pollutants such as chemicals, fumes, dust, and smoke can make it more difficult for people with dyspnea to breathe. People with asthma may find that exposure to allergens such as pollen or mold may trigger episodes of dyspnea.
Signs that a person is experiencing dyspnea include: shortness of breath after exertion or due to a medical condition. feeling smothered. Trusted Source. or suffocated as a result of breathing difficulties. labored breathing. tightness in the chest. rapid, shallow breathing.
Dyspnea is the medical term for shortness of breath, sometimes described as “air hunger.”. It is an uncomfortable feeling. Shortness of breath can range from mild and temporary to serious and long-lasting. It is sometimes difficult to diagnose and treat dyspnea because there can be many different causes.
The Dyspnea Lab, a research center specializing in shortness of breath, report that people find these programs helpful, even if the root causes of the problem remains. If tests indicate low levels of oxygen in the blood, supplemental oxygen may be supplied.
Diseases of the upper respiratory system that cause acute dysnpea are a relatively common pediatric emergency. They are one of the most common causes of shortness of breath in infants. Croup, inhaling a foreign object, and inflammation of the epiglottis are all common causes of dyspnea in infants.
Doctors may use chest X-rays and computed tomography (CT) images to make a more specific diagnosis of dyspnea and evaluate the health of the person’s heart, lungs, and related systems. An electrocardiogram (ECG) may help to show any signs of a heart attack or other electrical problem in the heart.
